Overview
The Brookfield BRS-10 Walk-in Environmental Test Chamber is an engineered solution for long-duration, large-scale environmental simulation in industrial quality assurance, materials aging studies, and product reliability validation. Designed according to the fundamental principles of convective heat and mass transfer, the chamber maintains precise, stable, and repeatable temperature and humidity conditions across volumetric test spaces ranging from 5 m³ to 200 m³—enabling full-size equipment testing, batch-level sample conditioning, or extended accelerated life-cycle evaluation. Its thermodynamic architecture integrates a high-efficiency refrigeration loop with dual-stage humidification and dehumidification subsystems, ensuring dynamic control fidelity within defined operational envelopes per IEC 60068-3-5 and ISO 16750-4 standards. The system operates under ambient conditions of 10–35°C and supports continuous operation at setpoints from RT+10°C to 100°C and 30–98% RH—making it suitable for both high-temperature drying protocols and high-humidity stress testing.
Key Features

- Interior constructed from electropolished AISI 304 stainless steel—corrosion-resistant, non-outgassing, and compliant with ISO 14644-1 Class 8 cleanroom requirements
- Exterior housing fabricated from cold-rolled steel with epoxy-polyester powder coating for mechanical durability and chemical resistance
- Forced-air circulation system featuring low-noise axial fans and optimized duct geometry to minimize turbulence and ensure uniform airflow distribution
- Comprehensive safety suite including ground-fault circuit interrupters (GFCI), overcurrent relays, thermal cut-off switches, and high-limit temperature sensors with independent alarm outputs
Sample Compatibility & Compliance
The BRS-10 accommodates heterogeneous test specimens—including automotive ECUs, medical device packaging, lithium-ion battery modules, aerospace composites, and pharmaceutical secondary packaging—without spatial constraint limitations inherent in benchtop chambers. Its scalable volume design allows for full-system thermal mapping per ASTM E741 and ISO/IEC 17025-accredited validation protocols. All control firmware and data acquisition logic are structured to support GLP/GMP-compliant audit trails, with optional integration into 21 CFR Part 11–compliant electronic record systems via RS485/Modbus TCP interfaces. Calibration documentation follows NIST-traceable practices, and chamber qualification reports may be generated in accordance with IQ/OQ/PQ frameworks.
Software & Data Management
The embedded controller provides native CSV export functionality for time-stamped temperature/humidity datasets, with configurable sampling intervals (1 s to 60 min). Optional PC-based software (BRS-DataLink v3.2) enables remote monitoring, historical trend analysis, deviation alerting, and automated report generation (PDF/Excel). Data integrity safeguards include write-protected memory buffers, cyclic redundancy checksums, and tamper-evident file headers. All logged parameters are timestamped using synchronized NTP clients when network-connected, satisfying traceability requirements under ISO/IEC 17025 Clause 7.7 and EU Annex 11.

FAQ
What is the standard lead time for custom volume configurations?
Standard delivery for base-model BRS-10 units (5–50 m³) is 8–10 weeks; custom volumes above 50 m³ require engineering review and typically ship within 14–18 weeks.
Can the chamber be integrated with a facility’s BMS or SCADA system?
Yes—Modbus RTU (RS485) and Modbus TCP (Ethernet) communication protocols are natively supported, with register maps provided for seamless integration.
Is third-party calibration certification available upon delivery?
NIST-traceable factory calibration certificates are included; on-site IQ/OQ validation services and UKAS-accredited calibration are available as optional add-ons.
What maintenance intervals are recommended for sustained accuracy?
Compressor oil and refrigerant levels should be verified annually; humidity sensor recalibration is advised every 6 months under continuous operation; air filter replacement is required quarterly.
Does the system meet CE marking requirements for export to the European Economic Area?
Yes—the BRS-10 complies with the EU Machinery Directive 2006/42/EC, EMC Directive 2014/30/EU, and Low Voltage Directive 2014/35/EU, and carries full CE documentation.
